DETAILED DESCRIPTION

In order to make objectives, technical details and advantages of the embodiments of the present disclosure apparent, the technical solutions of the embodiment will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the present disclosure. It is obvious that the described embodiments are just a part but not all of the embodiments of the present disclosure. Based on the described embodiments herein, those ordinarily skilled in the art can acquire other embodiment(s), without any inventive work, which should be within the scope of the present disclosure.
Monitoring values of railway signal devices are diverse; the monitoring values include monitoring values self-collected by the monitoring system and all monitoring values received by system interfaces corresponding to respective device types, which may basically be classified into switch quantities and analog quantities. A specific manifestation form of the switch quantity is real-time value of the switch quantity, change moment, change sequence or the number of changes. The switch quantity is a quantity having a finite number of states, and different states are usually denoted by numbers 0, 1, 2...n. For example, with respect to a track on a railway, states thereof include occupied by vehicle, idle without vehicle, uncollected, etc.; the occupied-by-vehicle state may be denoted by 0, the idle-without-vehicle state may be denoted by 1, and the uncollected state may be denoted by 3. An analog quantity is a quantity having a continuous value, for example, a voltage of a power supply screen, a track current, etc., and a specific manifestation form thereof is real-time value, average value, maximum value or minimum value.
Regardless of whether the switch quantity or the analog quantity, they may be collectively classified as an attribute, and the attribute is a numerical value. And each attribute belongs to one or several devices; and each device belongs to devices of one or several device types. According to systems to which the devices belong, the devices may be classified into different device types. For example, a device type of 25 Hz track contains many devices, for example, IG, IIG, 1705G, etc. And each device contains various attributes, for example, track occupancy state, track voltage, track circuit, etc. In use, it may be flexibly configured according to needs, and it is not fixed and unique. Thus, all the monitoring values displayed in the railway monitoring system may finally each come down to a certain attribute in a certain device in a certain device type, that is, classified according to the first level as device type, the second level as device and the third level as attribute, and these classified monitoring values are normalized; wherein, the device type includes, but not is limited to, frequency-shift track circuit, 25 Hz track circuit, turnout, signal, external power grid, switch machine and air conditioner; the device is defined as respective specific devices under the device type; the attribute is defined as a collection quantity contained under each device (specifically including a switch quantity or an analog quantity), and has a numerical value as a manifestation form thereof.
Through the above-described process of normalizing the monitoring values, various seemingly irrelevant data are integrated, so that the program in the centralized monitoring system does not need to care about a specific meaning of each collection quantity; regardless of whether each collection quantity is a switch quantity or an analog quantity, it may be classified as a certain attribute in a certain device of a certain device type. Therefore, in a subsequent use process, the operator may directly perform operations on attributes, such as taking value, taking change time, and taking upper and lower limits, etc., without worrying about whether the attribute is a switch quantity or an analog quantity, which lays a foundation for unification of the program.
According to a first aspect of the embodiment of the present disclosure, there is provided an alarming method for a railway monitoring system based on conditional expressions. Referring to FIG. 1, the method includes:
Normalizing a monitoring value, and acquiring a device configuration file;
Forming an alarm conditional expression and a restoration conditional expression according to the device configuration file, and inputting the same into an alarm configuration file;
Loading the alarm configuration file into a railway monitoring system, and checking whether an alarm condition is satisfied;
If the alarm condition is satisfied, exhibiting an alarm in a monitoring system; then checking whether alarm exhibition satisfies a restoration condition; if the restoration condition is satisfied, cancelling alarm exhibition in the monitoring system.
If the alarm condition is not satisfied, delaying for one second and returning to recheck whether the alarm condition is satisfied.
The alarm conditional expression contains one or more of analog quantity, switch quantity and historical alarm.
The checking an alarm condition includes: rechecking the alarm condition containing an attribute when an attribute value changes.
The checking whether an alarm condition is satisfied includes checking whether the alarm condition is continuously satisfied within configured delay time. If the alarm condition is continuously satisfied within the configured time, exhibiting an alarm in the monitoring system; if the alarm condition is not satisfied within the configured time, delaying for one second, and returning to recheck whether the alarm condition is satisfied.
If the restoration condition is not satisfied, delaying for one second, and returning to recheck whether the restoration condition is satisfied.
That the checking whether alarm exhibition satisfies the restoration condition includes checking whether the restoration condition is continuously satisfied within configured delay time, includes: judging, after starting alarm exhibition in the monitoring system, whether the restoration condition is continuously satisfied within the configured delay time; if the restoration condition is satisfied within the configured delay time, then cancelling alarm exhibition in the monitoring system and returning to recheck whether the alarm condition is satisfied; if the restoration condition is not satisfied within the configured delay time, delaying for one second, and returning to recheck whether the restoration condition is satisfied.
In an embodiment of the present disclosure, configuration file 1 is used to represent devices contained under a device type "25 Hz track circuit" and attributes contained under each device, and to point out a name of a switch quantity or an analog quantity corresponding to each attribute. Contents and the number of attributes under each device may be changed according to actual needs.
Configuration file 1:

DevType name="25Hz track circuit">
<Devs>
<Dev name="3G" >
<Prop name="track state" data="3GH switch quantity"/>
<Prop name="track voltage" data="3G track voltage"/>
</Dev>
<Dev name="IG">
<Prop name="track state" data="IGH switch quantity"/>
<Prop name="track voltage" data="IG track voltage"/>
</Dev>
</DevType>

The device configuration file 1 indicates that the 25 Hz track circuit has two devices 3G and IG, and each device contains two attributes of track state and track voltage.
According to the configuration file of the above-described 25 Hz track circuit, an alarm conditional expression is designed to implement track voltage analog quantity over-limit alarming, where, a symbol "." is used for separation to ensure clear meaning; each attribute is represented in a three-stage mode "device type. device name. attribute name" to uniquely determine an attribute; "device type. attribute name" is used to indicate that alarm conditions are checked respectively with respect to all devices under the device type.
The alarm conditional expression is:
(25 Hz track circuit. track voltage. value > 25 Hz track circuit. track voltage. upper adjustment limit) & (25 Hz track circuit. track state. value = 1)
Where, "25 Hz track circuit. track voltage" represents the attribute of "track voltage" under each device under the device type of "25 Hz track circuit". The symbol "&" represents an "and" operation.
The meaning of the alarm conditional expression is "checking each 25 Hz track circuit device, whether the track voltage is greater than an upper adjustment limit and a current track state is 1 (when the attribute is 1, it indicates that there is no vehicle pressing the track)".
When the above-described alarm conditional expression is loaded into the monitoring system program, it will start to detect each device under the "25 Hz track circuit", and take values for operation according to requirements in the alarm conditional expression; when an operation result is true, give an alarm; and when it is false, give no alarm.
It should be further noted that, in the present disclosure, when the alarm conditional expression operation result is true, before exhibiting an alarm to the monitoring system, it is necessary to further judge whether the configured delay time for alarming is satisfied, if it is satisfied, give an alarm; if it is not satisfied, delay for one second, and return to recheck the alarm condition.
After alarm exhibition, it is further judged whether the restoration condition is satisfied, so as to judge whether to cancel the alarm, and the restoration condition is set as:
(25 Hz track circuit. track voltage <= 25 Hz track circuit. track voltage. upper adjustment limit) & (25 Hz track circuit. track state. value = 1)
The meaning of the restoration condition is "checking each 25 Hz track circuit device, whether the track voltage is less than or equal to the upper adjustment limit, and the current track state is 1 (when the attribute is 1, it indicates that there is no vehicle pressing the track)".
At this time, if the track voltage in the 25 Hz track circuit device is less than or equal to the upper adjustment limit, cancel the alarm and return again to check the alarm condition.
It should be further noted that, in the present disclosure, when the restoration conditional expression operation result is true, before the monitoring system cancels alarm exhibition, it is necessary to further judge whether the configured delay time for alarm restoration is satisfied; if it is satisfied, cancel alarm exhibition; if it is not satisfied, delay for one second and return to recheck the restoration condition.
If the track voltage in the 25 Hz track circuit device does not satisfy the condition of being less than or equal to the upper adjustment limit, delay for one second and continue to judge whether the restoration condition is satisfied.
In another embodiment of the present disclosure, configuration file 2 is used to represent devices contained in the device type "external power grid", and attributes contained under each device, and to point out a name of a switch quantity or an analog quantity corresponding to each attribute.

    <Prop name="power factor" datatype="external power grid" data="line-I phase-C power

    </Dev>
    </DevType>

The configuration file 2 indicates that there are three devices in the external power grid: line I phase A, line I phase B, and line I phase A; each device contains seven attributes, i.e., voltage, current, frequency, active power, reactive power, apparent power, and power factor.

According to the above-described configuration file of the external power grid, an alarm conditional expression is designed to implement external power grid power outage alarming. The external power grid line-I phase-A power outage alarm conditional expression is configured as:

External power grid. line I phase A. voltage. value <= 143 & external power grid. line I phase B. voltage. value > 143 & external power grid. line I phase C. voltage. value > 143

Where, "external power grid. line I phase A. voltage." represents an attribute "voltage" of the device "line I phase A" under the device type "external power grid". The meaning of the alarm conditional expression is "checking whether a voltage attribute value of the line I phase A device under the device type of external power grid is less than or equal to 143 and whether voltage attribute values of two devices, i.e., line I phase B and line I phase C, are greater than 143."

When the above-described external power grid alarm conditional expression is loaded into the monitoring system program, it will start to detect each device under the "external power grid", and take values for operation according to requirements in the external power grid alarm conditional expression; when an operation result is true, give an alarm; and when it is false, give no alarm.

It should be further noted that, in the present disclosure, when the alarm conditional expression operation result is true, before exhibition an alarm to the monitoring system, it is necessary to further judge whether the configured delay time for alarming is satisfied, if it is satisfied, give an alarm; if it is not satisfied, delay for one second, and return to recheck the alarm condition.

After alarming, it is further judged whether the restoration condition is satisfied, so as to judge whether to restore alarming, and the restoration conditional expression is set as:

External power grid. line I phase A. voltage. value > 143

The meaning of the restoration condition is "checking whether the voltage attribute value of line I phase A under the device type of external power grid is greater than 143".

At this time, if the voltage attribute value of line I phase A under the device type of external power grid is greater than 143, restore alarming and return again to check the alarm condition;

If the voltage attribute value of line I phase A under the device type of external power grid does not satisfy the restoration condition of being greater than 143, then delay for one second and continue to judge whether the restoration condition is satisfied.

In another embodiment of the present disclosure, configuration file 3 is used to represent devices contained under the device type "switch machine", and attributes contained under each device, and to point out a name of a switch quantity or an analog quantity corresponding to each attribute.

The above-described configuration indicates that there are two switch machine devices, 3-J and 3-X in the switch machine; and each device contains a plurality of pieces of attribute information related to the device, such as normal position indication switch quantity, reverse position indication switch quantity, and normal position direct-current voltage.

According to the configuration file of the above-described switch machine, the alarm conditional expression is designed to implement turnout non-indication alarming; and the alarm conditional expression is configured as:

Switch machine. 1DQ relay switch quantity. value = 0 & switch machine. normal position indication switch quantity. value = 0 & switch machine, reverse position indication switch quantity. value = 0

Where, "switch machine. 1DQ relay switch quantity" represents the attribute of "1DQ relay switch quantity" under each device under the device type of "switch machine"; "switch machine. normal position indication switch quantity" represents the attribute of "normal position indication switch quantity" under each device under the device type of "switch machine"; and "switch machine. reverse position indication switch quantity" represents the attribute of "reverse position indication switch quantity" under each device under the device type of "switch machine".

The meaning of above-described switch machine alarm conditional expression is "checking each switch machine device, the 1DQ relay switch quantity has a value of 0, and the normal position indication switch quantity has a value of 0, and the reverse position indication switch quantity has a value of 0".

When the above-described switch machine alarm conditional expression is loaded into the centralized monitoring program, it will start to detect devices under each "special switch machine", take values for operation according to requirements in the alarm conditional expression, and alarm according to an operation result.

It should be further noted that, in the present disclosure, when the alarm conditional expression operation result is true, before exhibiting an alarm to the monitoring system, it is necessary to further judge whether the configured delay time for alarming is satisfied, if it is satisfied, exhibit the alarm; if it is not satisfied, for delay one second, and return to recheck the alarm condition.

Switch machine. normal position indication switch quantity. value = 1 (switch machine, reverse position indication switch quantity. value = 1; where, "|" represents an "or" condition;

The meaning of the restoration conditional expression is "checking each switch machine device, the value of the normal position indication switch quantity is 1 or the value of the reverse position indication switch quantity is 1".

At this time, if under the switch machine device type, the normal position indication switch quantity value is 1, and the reverse position indication switch quantity value is 1, then restore alarming and return again to check the alarm condition;

If the normal position indication switch quantity value and the reverse position indication switch quantity under the switch machine device type do not satisfy the restoration condition, then delay for one second, and continue to judge whether the restoration condition is satisfied.

In addition, contents in the alarm conditional expression may be varied, and secondary alarm may be performed according to other existing alarm results, which may implement more complex alarm logic while simplifying a logic expression. For example: the secondary alarm of the switch machine may be configured by using an alarm conditional expression below:

"Turnout. turnout non-indication. alarm state = 1 & turnout. turnout occupancy state, value = 1", which expresses that the current turnout is in a turnout non-indication alarm state and the turnout is in an occupancy state, and at this time, a new alarm, i.e., splitting switch alarm, may be generated.

By setting judgment of whether the configured delay time is satisfied in the entire alarming method, it may effectively prevent false alarms and repeated alarms of unrestored alarms, and avoid negative effects of asynchrony and instantaneous fluctuations in the analog quantity caused by inconsistency of alarm collection time of the switch quantity and the analog quantity that are interrelated. Meanwhile, by setting judgment of whether the restoration condition is satisfied, users may no longer be disturbed after restoring alarming, so that current device problems that need to be solved urgently may be paid attention to.

According to a second aspect of the embodiment of the present disclosure, there is provided an alarming apparatus for a railway monitoring system based on conditional expressions; the alarming apparatus includes modules below:

A normalization processing module: configured to normalize a monitoring value, and acquire a device configuration file;

An alarm conditional expression generating module: configured to form an alarm conditional expression and a restoration conditional expression according to the device configuration file, and input the alarm conditional expression and the restoration conditional expression into an alarm configuration file;

An alarm processing module: configured to exhibit an alarm in the monitoring system based on an operation result of the alarm operating module; and cancel alarm exhibition in the monitoring system when alarm exhibition satisfies the restoration condition.

The normalization processing module is configured to process a monitoring value self-collected by the monitoring system and all monitoring values received by system interfaces corresponding to respective device types.
